Be 1t lrnown that l, Jams d. Timor, 4a

citizen ci the lUnited States, and a resident a device of the kind in question, which may be readily affixed to a wind shield, or the like, without in any wise inarring the trame i ot the latter, or requiring the use or any tools, other than a wrench. At the same time the device is adjustable to insure the thorough cleaning action which is necessary it the device is to be oit use at all.

'lo the accomplishment oi the foregoing and related objects, the invention, then, consists ci? the means hereinafter lhilly described and particularly pointed out in the claimsa The annexed drawing and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one ci various mechanical terms in which the principle of the invention may be used.,

ln said annexed drawing s--F igure l is a side elevational view ot the device shown till as atlined to a wind shield ot anniliar construction, the latter appearing in lvertical. section; Fign 2 is a iront elevational view oit the device and a broken portion ot wind shield, as viewed trom the lett in Fig., l; Fig. 3 is a rear elevational view of device with the broken portion ot the wind shield as bollore, viewing the saine :trom the right in l; llig. l is a transverse section ot the devi talren on the plane indicated by the line l4f, Fig.. 3, and at the saine time illustrates the device as applied to a modified form ci wind-shield; and Fig. 5 is another transverse section taken 'on the plane indicated by the line 5-5, llig.. l.

rllhe principal operative 1element in the device consists ot a spindle l, carrying integral therewith a lever arm 2, such spindle and arm being conveniently fashioned out ot a single piece of rod, bent to the form clearly shown in Fig.. l. 'llhe spindle l, proper, is journaled in a bearing that is carried by one member 3 of a two-part clamping device, the other member l of which tits around the tubular extended portion 5 ot the lirst ineinber forming the bearin in question, and is adapted to Contact wit^ said rst member at a single point 6.. (Figs. l and 4t),

rlllhe members 3 and l are respectively :termed with downwardly depending bifurcated extension 7, 'l and 8, 8, olf similar -iorm,

z which terminate in inwardly directed ei @y lugs e, 9 and 10, l0, that are adapted to press againstI opposite faces or the Bpane ll. of glass in the wind shield, when the two members are drawn together by means et bolts l2 providedior this purpose.

ln applying the device to a wind shield, the two members 3 and l are iitted together ,and the depending portions 7 and 8 iitted over the top edge oi the wind shield trarne i3 until the device rests on such iframe; then by drawing up the bolts l2 the members are brought in contact at the point 6 and the ends 9 and l0 ot the bifurcations simultaneously pressed against the pane ll, the three-point contact that is thus secured between the two members insuring their perrect alinenient with the pane, and what is I more important, the perpendicularity or the axis' or the bearing 5 to such pane. When the members oit-theelamp are thus drawn together and the device `adjusted on the-wind shield, two set-screws le l5,

' carried by said members, respectively, are l adjusted to bear against the respective races of the iframe l so as to insure rigidity to the mounting. 1 y

lt will be observed that the bifurcations el2 the clamp members are long enough to entend below, not merely the circular metallic iframe 13 that is illustrated, because largely used in the construction ot wind shields, but also below a wooden trame lo of any ordinary or usual width, as illustrated in the modied construction of shield shown in Fig. l.

To the innerend ci the spindle l, which projects a short distance beyond the bearing in the inner clamp member, is secured an operatin handle l? of any desired torni and of suita le length to permit ofthe ready oscillation of the spindle with its 'recurved' lever-arm 2 on the outside of the shield,

lllli lll@ ' being preferably, near the mid point of the holder. The wiper is of rubber, or rubberized fabric, as is usual in devices of this sort, ybeing held in a groove in the inner edge of the holder. rlhe upper end of the holder is furthermore provided with two i outstanding ears 24, that laterally engage the lever arm 2, so that, when such arm is swung, the holder will be oscillated along therewith, while still being free to lie flat against the pane that is to be cleaned.

rilhe portion of the lever-arm 2,inwhich the set-screw 19 is mounted, being at right angles to the spindle 1, and the latter being securely held by the clamp members 3 and 4 at right angles to the pane of the-wind shield, it will be seen that the wiper-holder 22'will be in strict parallelism with the latter. Since the handle 17, secured as it is to the inner end of the spindle, will prevent movement of the latter in an outward direction in itsbearing, the adjustment of the set-screw 19 will be eective to vary the degree of pressure with which the wiper acts on the pane. v

l have foundl by practical experiment that sufficient resiliency will be secured in a lever arm of the substantial construct-ion shown, it being necessary as a matter of fact, if a device of this sort is to be at all effective, that considerable pressure be exerted on the glass to be cleaned. Bymeans of the present device, such pressure may be readily secured and wear of the wiper taken up, while it is an extremely simple matter to ailix the device lto any of the usual forms of wind shield. The simplicity of construction, together with the entire absence of any' springs or other parts that are apt to become loose and rattle, will additionally commend the device to the motorist.

In conclusion, it should be explained that inl usingy the term wind-shield, both"'in this specicationand the claims which follow, it is intended thereby to refer to the general structure, including the glass pane with its inclosing frame, where such a frame l is employed. Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed,

A provided the means stated by any `of the following claims or the equivalent of such stated means be employed.

a ,holder 22 that I l therefore particularly point out and p distinctly claim as my invention 1. ln a device of the character described, the combination of two relatively movable clamp members arranged ,to press against Opposite'sides of a wind-shield, or the like, respectively, one of said members including a tubularextension forming a transversely disposed bearing and the other member surrounding such extensionymeans adapted to ydraw said members together; a spindle rotatable in such bearing; an operating handle attached to one end of said spindle; and a wiper operatively connected with the other end of said spindle.
